Izzy just got a beautiful Pet Flys carrier and it's gorgeous. Problem is I can't get him to go in the whole bag. He will poke his head in every now and then, but then he jumps away from it. I tried putting treats in it and he'll go in and get them, then jumps right out with the treat. I'm getting desperate as it was an expensive gift and I'm dying to bring him to more places. Please does anyone have any new advice for me? do you think it's possible to get him to enjoy it? Thanks so much...
